3D Model (basic) – BETA

General:

genARate offers a basic pipeline for the integration and use of 3D models and animations

This content type is probably the most appealing one for augmented reality experiences

Please note that the current pipeline is still in BETA which means it is basically functioning, but not fully set up in all details – so you have to expect some restrictions and limitations especially around the UI as well as the 3D creation pipeline.

Note:

The “how to” section only covers the steps within the genARate Studio / genARate platform. For further information on how to create, export and convert 3D contents please have a look in section Creation Pipeline (further below)

How to:
  • Click on the 3D icon inside the toolbar to start the upload dialogue
  • Link the desired 3D file from your local drive
  • After the upload has completed the 3D model will appear in the scenario editor
  • Click on the 3D model inside the scenario editor to move/position the element via drag & drop and to access the settings
Settings:

Name:  Select a unique name for your 3D element

Source: Name of uploaded source file and button to replace uploaded 3D model “on the fly”

Size: Set individual size of 3D model (by width and height of ground plane – aspect ratio is fixed)

Position: Set individual position of model (by x and y – z not available, yet)

Rotation: Set rotation of model (by ° for 3 axis x,y,z)

Hidden: Makes model invisible at start of AR experience (to e.g. let it appear by a Button interaction at a later time)

Unique ID: Internal ID of content element, mostly used for referencing inside HTML fragments

Access 3D model from HTML Fragment: Unique link to 3D model, mostly used for referencing inside HTML fragments

Auto play: The animation of the 3D model (has to be provided inside the model) starts playing automatically when it appears in AR (if not, user needs to click 3D Model to start, etc.)

Continue playing: 3D Model stays visible, also when image tracking is lost (trigger image is not visible in camera view anymore), the 3D model will be displayed centered to the screen and user can rotate / scale it by touch interaction

Animations:

Explanation can be found here.
